Description

Technical Field

[0001] The utility model relates to the technical field of packaging sheet production, in particular to a cooling and shaping device for producing PVC medicinal packaging sheets. Background Art

[0002] At present, the main component of PVC is polyvinyl chloride, which is slightly yellow and translucent, shiny, more transparent than polyethylene and polypropylene, but worse than polystyrene. Depending on the amount of additives used, it is divided into soft and hard polyvinyl chloride. Soft products are soft and tough, and feel sticky. The hardness of hard products is higher than that of low-density polyethylene, but lower than that of polypropylene. Whitening will occur at the inflection point. Common products include: plates, pipes, soles, toys, doors and windows, wire sheaths, stationery, etc. It is a polymer material that uses a chlorine atom to replace a hydrogen atom in polyethylene.

[0003] Among them, a kind of high barrier performance medicinal packaging material is produced with polyamide, medicinal aluminum foil, polyvinyl chloride hard film and other materials as the base material through coating, compounding, curing and slitting. Its characteristics are: high barrier property, high adaptability, easy molding, good light-proof property, can completely isolate water vapor and oxygen, has good stretchability, and is easy to compound with aluminum foil into all-aluminum packaging.

[0004] However, the temperature of PVC rigid film is relatively high after production, which makes it difficult to roll it up. If it is rolled up immediately, it is easy to deform due to thermal expansion and contraction, which reduces the quality of the film and is not conducive to subsequent processing. Therefore, a new technical solution needs to be designed to solve the problem, which can efficiently cool both sides of the packaging film. Utility Model Content

[0010] As an optional solution of the technical solution of the present application, multiple groups of equidistantly distributed limit rings are installed on both sides of the first processing table and the second processing table. The multiple groups of limit rings are movably connected to each group of support frames respectively, so as to limit the support frames.

[0011] As an optional solution of the technical solution of the present application, a spring is fixedly installed on one side of each group of limit rings, and the other side of each group of springs is fixedly installed on the outer wall of the corresponding support frame respectively, so that the support frame can be supported.

When the liquid level sensor 24 detects that the liquid level inside the cooling roller 2 reaches the set value, the liquid pump 32 on the other side will be driven to deliver negative pressure to the water suction pipe 23 to extract the cooling water inside the cooling roller 2. The reciprocating operation can ensure that the cooling water continuously lowers the cooling roller 2, thereby efficiently cooling the packaging sheet.

[0023] In some technical solutions, multiple groups of equidistantly distributed limit rings 14 are installed on both sides of the first processing table 1 and the second processing table 11.
